ABSTRACT:
In a digital amplifier, a time controller generates first and second selection signals for outputting any one of music data, a center output, and a lowest output to a P output and an N output based on a power ON/OFF signal and a start/stop signal, and also generates a third selection signal for determining whether a signal having the same phase as that of the P output is output to the N output or a signal obtained by inverting the P output is output to the N output. A data selection circuit determines data to be output to the P output and the N output based on the first and second selection signals. An output data register circuit converts parallel data determined by the data selection circuit into serial data to output the serial data into the P output. An output selection circuit determines the N output based on the third selection signal.
